How Do I Reassemble The 3-way Threaded Ball Valve?

Reassembly

l Clean and inspect the disassembled parts of the 3 Way Threaded Ball Valve. It is strongly recommended to replace the valve seat and valve cover gasket and other seals with spare parts kits.

l Assemble the stainless steel ball valve in the reverse order of disassembly.

l Cross-tighten the flange connection bolts (5) with the specified torque.

l Tighten the valve stem nut (13) with the specified torque.

l After installing the actuator, input the corresponding signal to rotate the valve stem to drive the valve core to open and close the valve.

l If possible, please perform pressure sealing test and performance test on the valve according to relevant standards before reinstalling the pipeline.

Model indication method:

Like the previous valve Q11S-16C, the "S" indication is a relatively old method. "S" represents plastic seal. "F" represents PTFE or polytetrafluoroethylene material.
